Specification of Letters Patent. Patented uly 2 1918,

Application filed November 26, 1917. Serial 0. 203,871.

Z1; all whom it may concern:

Be it known that 1, PETER MEYER, a citizen of the United States, and aresident of Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in a Spring-Roll, and dohereby declare the following specification, taken in connection with,the drawings forming part of same, to be a full, clear, concise, andexact description of the inven; tion, so as to distinguish it from otherinventions. and to enable any person skilled in the art to which itappertains or with which it is most nearly connected to make, construct,and use the same.

This invention relates primarily to a spring or flexible roll and moreparticularly to a roll adaptedfor use in a hide splitting machine.

The invention contemplates as its primary object, a roll sufficientlyflexible to readily conform to an unevenand continually varying surfaceof an article passing between a set of rolls. --It is well knowninthehide splitting industry that the surfaces of hides vary greatly intheir unevenness and if the proper care is not'exerci'sed in splittingthe requisite number of splits is not attained.

:In machines where the maximumnumber of splits is obtained from eachhide, it has been found that splits are not uniform in thickness in thedifferent splits nor in the same split.

The present invention provides a means which readily adapts itself tothe varying irregularities of hides and other similar articles toproduce a maximum number of splits which are substantially uniform inthickness throughout and relatively to each other. 7

Another object is to provide a spring roll which can be rotated in anydirection applying power at either or both ends without impairing ordestroying the structure.

of the roll.

Another object is to provide a flexible means for connecting the endmembers of roll. 7

Another object is to provide an adjustable the end .members of the 1 pin9.

' site directions, suitably securing the ends of said windings inmembers provided at either end of said roll, and connecting said endmembers by a flexible and adjustable means. p I

Other objects will be apparent from, and are incorporated in the annexeddrawings, and in the following description which sets forth in detail,certain contrivances embodying means, constituting however, but one ofthe various mechanical formsin which the principle of the invention maybe used.

The novelty of the invention will be readily understood from thedrawings, which show a construction for practising the invention in itspreferred form, and from the. following description thereof, and is morespecifically pointed out and distinctly claimedin the claims annexed tosaid description.

cured in said flanges. In a similar manner convolutions 3; and- 4 areformed and secured whereupon the shaft upon which the wires have beenwound is withdrawn.

The flange 6 is provided with a cylindrical member'8 which is insertedafter the winding and is secured to said flange 6 by the 8 is providedwith a clutch 10 by means of which rotary motion may be imparted to thespring roll from any suitable source. The

other end of said cylindrical'member 8 isarother end of the tensionspring 12. A nut- 15 engages the threaded member 13 and is arrangedadjacent to the flange? By means" of the nut 15 the tension of thespring 12 can be varied to suit the requirements; A screw 16 in theflange? engages a's1ot-17- iirthe screw threaded member 13- to preventturning of said threaded member. The tension spring 12 extendsthroughout the entire length of the spring r011 and-isarra'nged so as tosubstantially coincide with'theaxisof the convolutions of wire.

The series of superimposed wire convo1utions can be'varied innumber tochange the degree of flexibility. The drawings show four wireswhich isthe number of windings best suited for splitting hides,

Ha vingdescribed my invention-I claim as new and desire to-se'cure byLetters Patent:

1. A roll consisting of'a series ofsnperimposed convolutions of wirewound alternately in opposite directions, aflange at each end of saidroll in which the ends-of the wires are secured, andia flexibleconnection between-said flanges.

2. A roll consisting of a series of superimposed convo1utions-- of wirewound alternately in opposite directions, a flange at eachend of saidroll inwhich the endsof the wires are secured, and an adjustableconnection between said flanges;

3. A roll consisting of a series of super imposed convolutions of wirewound alternately in opposite directions, a flange at each endOfsaidroll in which the ends of the wires are secured, and a tensionmember connecting said flanges.

4. A roll consisting of a series of superimposed convolutions of wirewound alternately in: opposite directions, a flange at each end of saidroll in which theends of the wires are secured, aflexibie tension memberconnecting said flanges, ancbmeans to adjust said member;

5: A- r011 consisting of a series of superimposed convohitio'ns of wirewound alternatelyinoppo'site directions, a flange at one end-of s'aidroll; a second flange at the other end of said roll, each ofsaicbflanges having secured therein theends of the wire, a memberse'curedto said'first mentioned flange, an adjustablemember arranged insaid second mention'ed flan'ge, and a spring connecting said members.

6.- A roll consisting of a series of super imposed convolutions of wirewound alternately in opposite directions, a flange at oneendofisaid-roll; a second'flange at the other end, eachofsaidflangesprovided with slots wherein the ends of the wires aresecured, a member secured to said first mentioned flange-and providedwith a clutch key, an
